Description
Technical Field
The present invention relates to charging rechargeable batteries of hearing aids, and in particular to a method for charging lithium ion batteries. The invention also relates to a hearing aid with a battery charging unit, in particular to a hearing aid powered by a lithium ion battery.
Background
Hearing aids (sometimes also referred to as hearing instruments or hearing prostheses) are small devices that are worn behind the ear or (at least partially) in the ear canal to compensate for the hearing impairment of hard-of-hearing persons. Such hearing aids are typically long-term and are powered by small batteries, such as zinc air button cells. Zinc-air batteries provide high energy capacity in small package sizes. However, in the case of hearing impaired persons using hearing aids for many hours each day, such batteries are often required to be replaced quite frequently, for example, every few days. The handling of such small batteries is particularly difficult and time consuming for elderly people who have lost their hands-on abilities and have degraded vision, when attempting to replace the depleted batteries of small hearing aids with fully charged batteries. Therefore, rechargeable batteries, such as, for example, nickel metal hydride (NiMH) or lithium ion accumulators, are increasingly used in hearing aids. However, rechargeable batteries have a lower capacity than zinc air batteries and thus the time period for powering the hearing aid is shortened. Thus, it may happen that the hearing aid is dead when the user travels or when the user forgets to recharge the battery the night before. Obviously, these situations are very inconvenient for the user, since the user often relies heavily on the hearing aid in operation to improve his hearing.
Therefore, appropriate means are needed to help the user to ensure that their hearing aid has sufficient power whenever it is needed.
Disclosure of Invention
It is therefore an object of the present invention to provide an improved method of charging a battery of a hearing aid, which ensures that the hearing aid has sufficient power whenever the user needs the hearing aid. This object is achieved by a method according to claim 1.
Furthermore, it is a further object of the invention to provide an improved hearing aid capable of supporting the proposed method. This object is achieved by a hearing aid according to claim 17.
Particular embodiments of the method and the hearing aid according to the invention are given in the dependent claims.
The invention provides a method for charging a rechargeable battery of a hearing aid, comprising the steps of:
detecting that a power supply is connected to the hearing aid;
estimating a state of charge of the battery;
selecting one of at least a normal charging mode and a fast charging mode according to the estimated state of charge; and is
And charging the battery according to the selected charging mode.
For example, when the user wants to leave the home and the charge level of the battery is low, by means of the proposed method it is possible to recharge the battery of the hearing aid quickly by using a fast charging mode. It is important to note that always applying fast charging will gradually deteriorate the battery capacity and therefore extensive use should be avoided and it should be limited to those situations where the user does need to be able to continue using his hearing aid for a certain amount of time.
In an embodiment of the method, the selection of the charging mode depends on one or more predefined criteria stored in a memory of the hearing aid or a hearing aid accessory such as a remote control unit. In this way, it can be ensured that the rapid charging is limited to a certain situation, in order to avoid deterioration of the battery capacity over time.
In a further embodiment of the method, the one or more predefined criteria are stored in a memory of the hearing aid or hearing aid accessory during fitting of the hearing aid to the hearing or preferences of the user of the hearing aid. In this way, the charging modes available to the user can be customized according to the user's needs.
In a further embodiment of the method the selection of the charging mode is further dependent on a user input, e.g. by a user operating a control element at the hearing aid or at the hearing aid accessory or at the power supply. In this way, the user can select a charging mode as desired, and can override the automatic selection or limitation imposed by the hearing aid, hearing aid accessory or power source, for example.
In further embodiments of the method, the selection of the charging mode further comprises providing information to the user regarding the battery state of charge, and presenting one or more possible selections to the user based on the battery state of charge. In this way, the user may be informed which charging mode is most appropriate in the current context, for example to enable the user to be aware of possible consequences of his selection of a particular charging mode.
In a further embodiment of the method the selection of the charging mode is performed automatically by the hearing aid. In this way, the user can be relieved of the pressure of having to make a selection, and the hearing aid can for example adopt the most appropriate charging mode based on the current situation, e.g. based on the current battery charge and/or the current use of the hearing aid (e.g. its operating state).
In a further embodiment of the method, the fast charging mode can be selected only when the estimated state of charge is below a first predefined threshold level of state of charge comprised in the one or more predefined criteria, in particular in the range of 5% to 50% of the (maximum) battery capacity. In this way, it is possible to not allow a quick charge when the charge level of the battery is still relatively high.
In a further embodiment of the method, the fast charge mode cannot be selected when the estimated state of charge is below a second predefined threshold level of state of charge comprised in the one or more predefined criteria, said second predefined threshold level indicating a deep discharge of the battery, in particular in the range of 0% to 5% of the (maximum) battery capacity. In this way, it is possible to prevent rapid charging when the battery is deeply discharged, because performing rapid charging in such a case may cause damage to the battery.
In a further embodiment of the method, charging the battery comprises a constant current charging phase during which the charging current is kept constant and a constant voltage charging phase during which the charging voltage is kept constant, and wherein charging in the fast charging mode employs a higher charging current during the constant current phase than charging in the normal charging mode, and wherein charging is switched from constant current charging to constant voltage charging when the battery voltage exceeds a predefined threshold level comprised in the one or more predefined criteria.
In a further embodiment of the method, the duration of the constant current charging phase for charging with a higher current in the fast charging mode is limited to a maximum time interval comprised in the one or more predefined criteria, in particular in the range of 1 to 5 minutes, after which the charging switches to another charging mode, in particular to the normal charging mode. In this way, excessive rapid charging can be prevented so as to maintain the durability of the battery capacity.
In a further embodiment of the method, the predefined threshold level of the battery voltage determining the switching from constant current charging to constant voltage charging is different for a fast charging mode and a normal charging mode, these two associated predefined threshold levels being comprised in the one or more predefined criteria, in particular the predefined threshold level of the battery voltage being higher in the fast charging mode than in the normal charging mode.
In a further embodiment of the method, the fast charge is terminated upon determining that the current state of charge of the battery exceeds a third predefined threshold level of state of charge comprised in the one or more predefined criteria, the battery capacity associated with the third predefined threshold level of state of charge being especially sufficient to power the hearing aid for a period of time in the range of 1 hour to 2 hours. In this way, a certain run time of the hearing aid is ensured, while excessive fast charging is avoided, in order to maintain the durability of the battery capacity.
In a further embodiment, the method further comprises recording information about at least one of:
a state of charge at the start of charging the hearing aid;
a duration of a charging cycle (cycle);
a total number of fast charge cycles or mode selections;
a total number of normal charging cycles or mode selections;
a total number of charging cycles;
a total number of user-initiated fast charge cycles.
This recorded information can be used to determine the remaining life of the battery and provide information to a user, assembler, or other service provider, for example, when the battery needs to be replaced. Further, the charging of the battery can be adjusted based on such recorded information.
In a further embodiment of the method, the fast charging mode will not be able to be selected when the total number of fast charging cycles or mode selections performed exceeds a predefined maximum number of fast charging cycles comprised in the one or more predefined criteria, the maximum number of fast charging cycles in particular being in the range of 500 to 5000. In this way, it is possible to prevent excessive use of the quick charge so as to protect the battery.
In a further embodiment of the method, the selection of the charging mode further comprises providing the user with information about the remaining number of allowed fast charging cycles, in particular the difference between the predefined maximum number of fast charging cycles and the total number of previously performed fast charging cycles or mode selections. In this way, the user can be always aware of how frequently the quick charge is employed, and can be made aware of the excessive use of the quick charge.
In a further embodiment of the method, the rechargeable battery is a lithium ion battery, for which the proposed method is particularly advantageous.
In a further embodiment of the method, estimating the state of charge comprises measuring a voltage level of the battery and/or based on data recorded by the hearing aid relating to measurements of battery current and/or capacity. In this way, the state of charge of the battery can be accurately and reliably determined.
Furthermore, the present invention provides a hearing aid comprising:
a sound pickup;
a speaker;
a processing unit adapted to process an input audio signal picked up by the pickup and to provide a processed audio signal for output by the speaker;
a rechargeable battery for powering the hearing aid;

a connection unit adapted to operatively connect a power source, such as a current source or a voltage source, to the hearing aid; and

By incorporating the charging unit into the hearing aid, a simpler power supply can be employed, while providing the specific "intelligence" needed to charge the hearing aid in the hearing aid itself. Furthermore, the hearing aid for example has information about its usage (current, previous and predicted future usage), on the basis of which the charging scheme controlled by the charging unit (e.g. in cooperation with the processing unit) can be optimized.
In an embodiment of the hearing aid, the charging unit is controlled by the processing unit. In this way, the optimization of the charging process can be further improved.
The charging unit and the processing unit are particularly adapted and configured to support charging of a hearing aid according to the method of the invention.
In a further embodiment of the hearing aid, the charging unit or the processing unit is adapted to automatically select the charging mode in accordance with one or more predefined criteria stored in a memory of the hearing aid or of a hearing aid accessory such as a remote control unit.
In a further embodiment, the hearing aid further comprises or is operatively connectable with a user control element operable by a user of the hearing aid to select the charging mode, the user control element being in particular arranged at a hearing aid accessory such as a remote control unit or at the power supply.

Drawings
The invention will be further explained below by means of non-limiting specific embodiments with reference to the attached drawings, in which:
fig. 1 depicts a schematic block diagram of a hearing aid according to the invention.
Detailed Description
In fig. 1 a hearing aid 1 according to the invention is schematically illustrated. The hearing aid comprises: a microphone 2 for picking up sound from the surroundings of a user wearing the hearing aid 1 at the ear or at least partly in the ear canal; a processing unit 4 for processing, e.g., amplifying, the audio signal from the sound pickup 2; and a micro-speaker 3 (often also referred to as a receiver) for outputting the processed audio signal into the ear canal of the user. The hearing aid 1 is powered by a rechargeable battery 5, such as for example a lithium ion button cell. Since the hearing aid 1 is typically used for a long period of time (e.g. a whole day), the battery needs to be recharged the first night. For example, when high amplification or large amounts of processing are required, for example due to frequent changes in the listening environment or due to the use of power intensive features (e.g. beam forming, feedback cancellation or audio streaming), the widespread use of hearing aids 1 will cause the battery to drain more quickly, thus requiring the hearing aid 1 to be recharged during the course of the day. The charge level detector 6 monitors the state of charge of the battery 5, and notifies the user, for example, via a signal output by the speaker 3 when the battery 5 becomes short of electric power. If the user urgently needs the hearing aid to remain operational, he will find it very useful to be able to quickly charge the battery 5 to a level that at least allows the hearing aid 1 to be powered in 1 to 2 hours. The user can initiate a fast charge of the battery 5 by connecting the hearing aid 1 to the power supply 8 and e.g. pressing a fast charge button 12 on a user control device 11, such as a remote control unit. The button 12 may also be located on the hearing aid 1 itself or may be arranged at the power supply 8. The power supply 8 may be connected with the hearing aid 1 via wires and electrical contacts or may wirelessly transfer power to the hearing aid 1, e.g. by means of capacitive or inductive coupling.
The charging process is controlled by the charging unit 9, possibly in combination with the processing unit 4, taking into account the estimated state of charge of the battery 5 provided by the charge level detector 6. The charging unit 9 and/or the processing unit 4 may automatically select the charging mode according to one or more predefined criteria stored in the memory 10 of the hearing aid 1. Alternatively, such data may be stored in a memory of a hearing aid accessory 11, such as a remote control unit, which is operatively (e.g. wirelessly) connectable with the hearing aid 1.
Information about the current state of charge may be provided to the user, along with possible charging options, on a display located, for example, on the hearing aid accessory 11, so that the user can select the appropriate charging mode. In this way, guidance can be provided to the user as to how many fast charge cycles can also be applied to the battery 5 without causing damage. Furthermore, the user can for example be informed that a quick charge is not available, for example allowing continued use of the hearing aid 1 because the power level of the battery 5 is sufficiently high, or that a quick charge would cause damage to the battery 5 because the battery 5 is deeply discharged.
In order to provide such information to the user, it would be useful to record data regarding the charging of the battery 5 in the hearing aid memory 10 or alternatively in a memory of the accessory 11, such as a remote control unit. This recorded data can also be used to determine the remaining life of the battery 5 and provide information to a user, assembler or other service provider, for example, when the battery 5 needs to be replaced. Further, the charging of the battery 5 can be adjusted based on the recorded data.
Since the increased constant current employed during fast charging can significantly cause degradation of the capacity of the battery 5, the present invention ensures that fast charging is only effective for a short period of time (e.g., by limiting the period of time of the constant current phase (with increased charging current) of the charging cycle). Furthermore, the fast charge is optimized to ensure that the charge level allows the hearing aid 1 to operate for one to two hours.
The present invention provides an improved hearing aid 1 that allows for the management of charging in a more user-friendly manner. The proposed method for fast charging provides a good trade-off between battery life and temporary user demand. A further advantage of the invention is that the entire hearing system is simplified, since the charging is controlled by the hearing aid 1 itself. This will lead to reduced costs and higher efficiency, since the charging unit 9 (which can be part of the processing unit 4 or integrated with the processing unit 4) controlling the charging process is integrated into the hearing aid 1, thus enabling a simpler, more general (but "silent") power supply.
